Secondly, engine performance will need to be tested, along with the quality of the engine oil and any other fluids. In addition, if available, a diagnostic scan will usually provide a lot of detail on the condition of the car, so this should also be taken into account before purchasing.
Overall, it is possible to buy a high mileage diesel car, but it is crucial to exercise caution and do proper research on the car beforehand to make sure that any potential issues are identified and addressed.
Why do diesels last longer?
Diesel engines are designed to last much longer than gasoline engines due to their construction and design. Diesel engines are known to be stronger and more durable than gasoline engines, and this makes them inherently more reliable.
Diesel engines typically last much longer than gasoline engines because they don’t have spark plugs which can fail over time. This eliminates a major potential problem that gasoline engines can face.
Further, diesel engines don’t require as much maintenance as gasoline engines because they typically don’t suffer from such severe carbon build-up. This carbon build up is created when the air-fuel mix isn’t properly balanced, and this can be difficult to maintain with a gasoline engine.
Also, diesel engines typically use lubricating oil that is more heat-resistant than the oil used in gasoline engines, which leads to a longer engine life. The diesel fuel itself also helps to add engine life to the diesel engine because it doesn’t require as many cleanings as gasoline engines do.
Finally, diesel engines don’t have as many moving parts, so the risk of troublesome mechanical or electrical problems is lower. All these factors help to create an engine that lasts much longer than a gasoline engine.
Is 20 year old diesel fuel still good?
Unfortunately, it’s difficult to give a definitive answer to this question, as the quality of diesel fuel deteriorates over time even when it is stored properly. Generally, diesel fuel has a shelf life of between 6 months and 1 year, so any diesel fuel older than that has likely begun to break down and could be of questionable quality.
In addition to age, other factors come into play when determining if diesel fuel is still good, such as how it has been stored and the temperature at which it has been stored. If the diesel fuel has been stored in a clean, airtight container out of direct sunlight and at temperatures between 45-75°F, then it may still be of good quality.
However, if diesel fuel has been stored improperly and in extreme temperatures, it could be of poor quality and should be replaced. For this reason, if the diesel fuel in question is more than one year old, it is recommended that you replace it to avoid any potential problems.
Do diesel engines last longer than gas?
The answer to this question is that diesel engines can be expected to last longer than gasoline engines. This is due to several factors including the difference in the composition of the two fuels, the added durability and performance of diesel engines, and their design.
Diesel and gasoline are composed of different components. Diesel fuel contains more lubricating compounds, which can protect the engine’s internal components, while gasoline contains more volatile compounds, which can result in engine deposits, higher operating temperatures and more wear on parts.
Diesel engines are also designed to be more durable than gasoline engines. Diesel engines are built to withstand the higher pressures generated during combustion, which means they normally have larger, heavier-duty parts.
Additionally, diesel engines have a better thermal efficiency than gasoline engines, which translates to less heat-related wear and tear on the components in the engine. Diesel engines also are not subject to the same level of spark plug wear that gasoline engines are, as diesel engines have glow plugs or heaters to ignite the fuel/air mixture.
Therefore, these engines have fewer parts that need to be replaced.
Overall, due to the composition of the fuel, the design of the engine, and the added durability and efficiency of the diesel engine, they can be expected to last longer than gasoline engines.
